What visor fits the AGV K1? Start with two checks: the exact model name printed in your helmet (K1 or K1 S), and the size label inside it, because AGV sells the visor it lists for the K1 S in two helmet-size versions. We list 25 options in our AGV K1 category across replacement visors, photochromic visors and anti-fog inserts, and this page puts the K1 listings first.
Aftermarket visors for the AGV K1
Helmet size matters
AGV’s own parts listings name the K1 S on one visor with the K5 S and K3 SV, and sell it in two versions by helmet size. For the K1 S those versions are:
- XS-S-M helmets
- L-XL-XXL helmets
Check the size label inside your helmet and match it to one of those two ranges before you choose a listing. The K5 S and K3 SV ranges on the same visor are labelled differently (XS-S-MS and ML-L-XL-XXL), so do not mix the two sets up. You can read AGV’s parts listing for the smaller-size version on agv.com.
We do not state a size range for any listing on this page. Our supplier does not say which version the listings marked below are, and the same check applies to any visor listing that names the K1 S, K5 S or K3 SV.
What visor fits the AGV K1? The K1 listings
Replacement visors from $21.99
The K1 has a listing that names it on its own, followed by listings that name the K1 S and K1 together with other helmets. Pick the tint to suit when you ride, and see all our replacement visors for more.
- AGV K1 Replacement Visor — Smoke, Clear Tints
- AGV K1 S / K1 / K5 S / K5 Replacement Visor — Iridium, Smoke, Clear Tints (check your helmet size first)
- AGV K1 S / K1 / K3 SV / K5 S & more Replacement Visor — Iridium, Smoke, Clear Tints
- AGV Compact ST / K1 S / K1 / K3 SV & more Replacement Visor — Iridium, Smoke, Clear Tints
Photochromic visors from $61.99
One photochromic visor darkens in bright light and clears when it dulls, which suits a rider who would otherwise carry a clear and a dark visor.
- AGV K1 S / K1 / K5 S / K5 Photochromic Visor (check your helmet size first)
- AGV Compact ST / GT4 / K1 S / K1 & more Photochromic Visor
- AGV GT2 / GT4 / K1 S / K1 & more Photochromic Visor
Anti-fog inserts from $16.99
An anti-fog insert goes inside the visor you already own, so it suits a visor that is fine but fogs in cold or wet weather.
- AGV K1 S / K1 / K3 SV / K5 S & more Anti-Fog Insert — Stops Visor Fogging
- AGV Compact ST / GT4 / K1 S / K1 & more Anti-Fog Insert — Stops Visor Fogging
- AGV GT2 / GT4 / K1 S / K1 & more Anti-Fog Insert — Stops Visor Fogging
Reading the other names in K1 listings
- K1 and K1 S. AGV’s own titles name the K1 S. Several of our listings name the plain K1 as well, and one (AGV K1 Replacement Visor — Smoke, Clear Tints) names the K1 on its own, so go by the exact name on your helmet.
- GT2 and GT4. In some of our listing names these are visor codes, not helmet models. Match your helmet’s name in the listing’s model list rather than the code in the title.
- Compact ST. AGV lists the Compact ST’s visor as its own part, shared with the Compact and Numo Evo ST. A listing here that names the Compact ST beside the K1 S is how we have grouped it, so order only from a listing whose model list names your helmet.
Manufacturers reuse model names across redesigns, so match the name inside your helmet or on the original visor, plus any revision or year suffix, before you order. The full AGV picture is in our guide to the Compact ST, GT4, K1 and K1 S listing group.
Our visors are aftermarket and unbranded — the AGV name indicates fitment compatibility only, not an official AGV part.
Tint and road use
In Great Britain the legal test is the marking on the visor, not its colour: an eye protector has to carry a BS 4110 grade with an approved certification mark, or an ECE 22.05 approval, on the visor itself. Mirrored, iridium and dark-smoke finishes transmit too little light to be legal for road use in Great Britain, day or night — treat them as track or off-road only. We do not verify markings on individual items, so we make no road-legal claim for anything we sell, and rules differ in other countries. Northern Ireland has separate legislation we have not researched. This is general guidance, not legal advice. There is more detail in our guide to whether iridium and mirrored visors are road legal.
The legislation is the Motor Cycles (Eye Protectors) Regulations 1999, published on legislation.gov.uk.
